FITTING FOR SYSTEMS UTILIZING HIGH PRESSTIBE.

To all whom it may concern. Be it known that I, Gnonen W. SAVAGE, a citizen of the United States, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented a certain new and useful Fitting for Systems Utilizing High Pressure, of which the following is a specification.

The invention, generally stated, has relation to afitting employed in systems utiliz- --ing high pressure, as for instance, gas, alr,

ticular relation to the providing of a fitting vidin steam and like systems and has more parfor use in connection with high pressure gas systems used for illuminating purposes in residences, business houses and the like.

The principal object of the present invention is to provide a fitting embracing few parts, which may be economically manufac-. tured, readily assembled, positioned and set for efficient use without further regulation and which parts when so positioned shall be interlocked and sealed so that tampering with the valve and valve rod thereof by unau thorized persons cannot readily be accomplished or which in any event cannot be ac complished without the factof such tampering being brought tothe attention of an authorized agent inspecting the system to which the fitting is att'ached, thereby promaximum safetyfor the user." rther object of the invention is to provide a fitting of the above type in which the valve thereof when once positioned(except for cleaning, repairing or the like purposes) does not require regulation and which valve when so positioned abuts at its rear end against a supporting structure in order to relieve certain of the fitting parts of the effect of pressure of the medium passing through the fitting.

A further object of the present invention resides in the providing a new andnovel v form of combined valve-rod shield or cover and operating handle whereby when the shield. is in place upon the fitting the valve-v rod is protectedand completely hidden from view and whereby when such shield is detached may be, readily fitted to the valverod for operating the same.

' Other and further objects of the invention reside in the providing of a new and novel valve attachment for clearing the'valve seat of deposits and in the providing of. the fitting with a deposit or drip chamber.

Other and still further objects reside in the providing of general ,details of construction and arrangement of'parts as will here- I inafter more fully appear.

The invention consists. of the improvements hereinafter described and finally claimed.

The nature, characteristic features: and scope of the invention will be fnore fully understood from the following description taken in connection with the accompanying drawings forming part hereof and in which Figure 1, is a new in central section of a v fitting embodying the invention, Fig. 2, 1s a view in horizontal section taken upon .the' line-22of Fig. 1, and Figs. 3a and 4, are views taken upon the lines 33, and 4-4, respectively, of Fig.1."

In, the drawings the fitting is of general cruciform configuration, see Fig. 1, and in manufacture is made up of a very small number of parts, five by actual-count, thus f insuring cheapness of, manufacture, simplicity of construction and efficiency in use.

As the parts all have screw-threaded rela-\ tion with one another the fittingmay be readily assembled. The part 10, of the fitting, is of angular construction and. embraces ahorizontal inlet connection 11, a

vsimilarly disposed extension 12, an upwardly extended outlet connection 13, and a depending extension 14, constituting a com bined expansion and depositor dripcham-i her, all of which parts are integral," These extensions and connections are arranged at at i right angles to one another. 'The inlet con-j nection 11, has extendedthereacross andintegral therewith a partition, centrally aper tured to provide a valve-seat 15.. Fitted to the extension 12, so that its forward end pr0-' jects'well into the vertical bore, of the part 10, is a one piece horizontally disposed bushing 16, provided'with ahexagonal part-17, terminating in a forwardly extended "shouL der 18, and a rearwardly extended sc'rew threaded portion 19.; Having screw threaded relation withthe bushing 16, so as'to be ice movable endwise therethrough is a valvestem 20, provided ,witha valve 21, for '00- both for opening-"and closi g theopening 1 therethrough and-for cleanslng the same of operative engagement with the 'valveiseat 15.,

deposits which may be present by means of the drill point 22, projected from the valve 21-, which has a nice sliding fit with said suitably packed as at. 26.

sitely disposed beveled parts 23, and 24, for

a purpose to presently appear.

The outer end of the valve-rod is squared at 25, to receive an operating device hereinafter to be described. The valve-rod is Having screw threaded relation with the part 19, of the bushing 16, and completely inclosing and hiding entirely from view the valve-rod isa shield or hood 27. The shield abuts against the part 17, of the bushing 16, and the shoulder 18, of the bushing in turn-abuts against the extension 12, of the part 10, so

that from end to end the valve-rod is completely inclosed. That part of the shield 27 which normally is adjacent the bushing end is provided with a boss 28, having formed therein'a squared opening 29, of a size for operatively engaging the squared end 25, of

the valve-rod so that the-shield may be used as an operating handle when detached from the fitting. The boss 28, has also drilled therein a small opening 30. A lug 33, formed integral with the extension 12, of the part 10, has also drilled therethrough a small opening 32. In practice a wire seal 31, is

used for sealing the shield with respect to the part 10, the wire of the seal being passed through the openings 30, and 32, whereby to remove the shield to operate the valverod, it is necessaryto break the seal. The seal 31, is usually located beneath the fitting as shown. "Thus unauthorized persons are not apt to tamper with the fitting and should they do so an authorized agent inspecting the system has knowledge of such act so that a thorough inspection follows. In practice, and speaking now particularly of the use of high pressure gas in residences, business houses and the like, the fitting parts are so constructed that when once Set, no adjustments are necessary for eflicient operation. In this connection, it may be stated that the relative position of the valve-21, to its valve seat 15,. as shown, in' the drawings is proportioned for this result. It will be noted that the bushing 16, is extended outwardly 'so that the beveled part 23, of the valve will when in closed position, forms a snug fit with respect to the opening in the valve seat 15.
